We have carried out a further study of the behavior and
physical properties of the dwarf novae UZ Ser, X Leo and CN
Ori during quiescence, using archival IUE NEWSIPS spectra.
Previous studies (Henry and Sion 2001; Urban et al. 2001)
determined the best-fitting white dwarf models and
best-fitting accretion disks to the quiecent spectra but did
not use combinations of disks and photospheres along with
the best distance estimates. We have re-ananlyzed the three
systems with composite disk plus photosphere models and
present the results along witht their implications..
